Abstract

Three novel unsymmetrical vanadyl dodecakis(2,2,2‐trifluoroethoxy)phthalocyaninates with nitro, amino or with no substitution were synthesized by a statistical condensation of 3,4,5,6‐tetrakis(2,2,2‐trifluoroethoxy)phthalonitrile with 4‐nitro, 4‐amino or 4‐unsubstituted phthalonitrile, and separated by common column chromatography. These highly soluble phthalocyanines were characterized by elemental analysis, ir and ^1^H‐nmr, uv‐visible and fast‐atom‐bombardment mass spectroscopy. Their uv‐visible absorption spectra in solution and in doped poly(methyl methacrylate) films showed that they were less aggregated unsymmetrical phthalocyanines.
